Understanding the Role of Domain Name Server (DNS)

What is DNS?

DNS stands for Domain Name System and is an integral part of the internet. It is a distributed database that maps domain names to IP addresses. This allows computers to easily locate services, websites and other resources on the internet without having to remember a long string of numbers.

How does DNS work?

DNS works by translating a domain name into its associated IP address. When a user types a domain name into their web browser, their computer will first contact the DNS server and request the IP address associated with that domain name. The DNS server then looks up the IP address in its database, and returns it back to the user’s computer so that it can connect to the correct server.

In addition to providing IP addresses for domain names, DNS is also used to provide other types of information about the domain, such as email servers and various services related to it.

Why is DNS important?

DNS is important because it makes it easier for us to access websites and services, since we don’t have to remember IP addresses. It is also important for security, since some malicious actors use address spoofing to trick users into accessing malicious websites. By using DNS, users can ensure that they are connecting to a legitimate website.

Finally, DNS helps to improve the performance of the internet by providing a way for redundant services to be spread across multiple servers.

Short Note

Def: DNS is use for converting the into IP address.
